The above modules 154, 156, 158, 160, 162 and their functions will be described in further detail in relation to an exemplary method below.

As shown in the example of FIG. 2 , a user account communications interface 200 for accessing and communicating with the platform 140 and displayed at a computer device 150. The interface 200 provides access to video data, audio data, chat data and meeting transcription related to an online event(s), such as a virtual webinar or a virtual meeting joined by a user account associated with the computer device 150. The interface 200 further provides various types of tools, functionalities, and settings that can be selected by a user account during an online event. Various types of virtual meeting control tools, functionalities, and settings are, for example, mute/unmute audio, turn on/off video, start meeting, join meeting, view and call contacts, send/read chat message and/or provide edits/inputs to a whiteboard functionality. The platform 140 generates historical online event data, such as historical virtual meeting data and historical online webinar data, based on user account behavior exhibited at least via the interface 200. In various embodiments, the interface 200 may be generated by a client software application associated with the platform 140.

As shown in diagram 300 of the example of FIG. 3 , prior to initiation of a virtual meeting, the Mesh Orchestrator 302 defines a mesh of mesh parent client computer systems and mesh children client computer systems. The Mesh Orchestrator 302 sends message to each client computer system of a mesh that has been designated the role of mesh child. For example, the message may be a child designation message indicating to a particular client computer system that is has been assigned the role of being a mesh child. In addition, the child designation message further identifies a specific mesh parent from which the mesh child should request the virtual meeting stream when the virtual meeting begins.

Upon initiation of the virtual meeting, each mesh parent 306, 308 of a mesh instance 304 requests the a media stream of the virtual meeting from a media server 310. The media server 310 may be a cloud-based media server or may be an on-premise media server. In some embodiments, an organization may have a plurality of client computer systems that each run client application software for accessing and using a video communication environment that provides for the scheduling and hosting of various online event, such as virtual meetings, online webinars, online video calls, etc. The organization may use a content distribution network that sets a maximum allowable bandwidth allocated for the video communication environment. In the past, user accounts would typically login to online webinars from a personal residence location via a video communication environment client software application. However, recent user account behavior has evolved, and a recent trend shows that user accounts prefer to login to online webinars from their office or assigned physical workspaces. The maximum allowable bandwidth allocated for the video communication environment on the organization's content distribution network may be reached when a large number of on-site user account logon attempts occur for the same online event

In order to avert oversubscription of network bandwidth, prior to initiation of an upcoming online webinar, the Mesh Orchestrator 302 identifies client computer systems at a same logical location that are associated with user accounts that are scheduled to login to the upcoming online webinar via the video communication environment. Prior to a start of the online webinar, the Mesh Orchestrator 302 accesses data related to the identified client computer systems that was generated by the video communication environment. For example, the Mesh Orchestrator 302 accesses historical virtual meeting data of each of the identified client computer systems and other types of data. By analyzing the accessed data, the Mesh Orchestrator 302 defines a mesh 304 of the identified client computer systems. By defining the mesh 304, the Mesh Orchestrator 302 selects one or more of the identified client computer systems to act as a mesh parent and all other identified client computer systems are designated as a respective mesh child. For example, the Mesh Orchestrator 302 ranks the identified client computer systems based on each computer system's historical virtual meeting data. Higher ranked computer systems are candidates for the mesh parent role. Lower ranked computer systems are candidates for the mesh child role.

Prior to a start of the online webinar, the Mesh Orchestrator 302 runs various tests on the defined mesh 304 and further defines contingency logic. For example, the contingency logic may include one or more commands for changing a mesh definition and/or mesh instance while the online webinar is actually being streamed. Such contingency logic commands may include commands for changing a mesh parent, changing a mess child and/or setting a type of visual display layout (i.e., user interface configuration) that must be used by one or more of the mesh client computer systems that have actually logged onto the online webinar. As the online webinar is initiated, the Mesh Orchestrator 302 instantiates a version of the mesh 304 (i.e. mesh instance) based on the defined mesh 304 and the mesh client computer systems that are actually logging onto the online webinar. Once the mesh instance has been implemented, each mesh parent 306, 308 requests the online webinar's media stream from a media server and each mesh child requests the online webinar's media stream from a particular mesh parent 306, 308 identified in a received child designation message.

As shown in diagram 400 of the example of FIG. 4 , the Mesh Orchestrator 302 confirms an availability status of one or more of the respective client computer systems associated with those identified user accounts scheduled to attend (i.e., log onto) an online event. In some embodiments, the Mesh Orchestrator 302 detects that one or more particular computer systems at a logical location and included in a previously determined mesh definition are currently unavailable. At a moment of time proximate to (or concurrent with) a start time of the online event, the Mesh Orchestrator 302 instantiates a mesh instance 402 according to the mesh definition. However, the mesh instance 402 will be a grouping of the computer systems identified in the mesh definition that is further based on a modification of the mesh definition due to the unavailable computer systems. As such, the mesh instance 402 will be instantiated only with currently available computer systems that were also previously indicated for inclusion in the mesh definition. For example, the mesh instance 402 includes a mesh parent computer system 404 that was previously designated in the mesh definition to act as a mesh child and as a back-up mesh parent (i.e., secondary mesh parent). However, contingency logic updates the mesh child designation in order to designate the corresponding computer system to act as the mesh parent 404 in the mesh instance 402 as result of the Mesh Orchestrator 302 detecting that an initially designated mesh parent computer system is currently unavailable.

As shown in flowchart 500 of the example of FIG. 5 , prior to initiation of an upcoming virtual meeting, the Mesh Orchestrator identifies one or more user accounts scheduled to participate in an upcoming virtual meeting delivered via a video communication environment (Act 510). For example, the video communication environment may have a client software application that is installed on one or more client computer systems at a logical location. The client software application may include a scheduling functionality for scheduling one or more online events. The scheduling functionality may further be integrated into (or include) a calendar functionality.

The Mesh Orchestrator accesses calendar data and identifies user accounts that are scheduled to attend an upcoming virtual meeting and further determines whether any of the user accounts are associated with a client computer system from a particular logical location. A logical location may be one or more network segments where the client computer systems are connected to a local area network (wired or wireless/wifi) and can communicate directly with one another through bi-directional L3 connectivity. Typically, a location will have limited bandwidth northbound either through a WAN connection and/or DIA (direct internet access). In some embodiments, a logical location may be explicitly defined and configured in an administrator portal of the video communication environment where groups of subnets are combined into the logical location. The maximum amount of bandwidth available to a particular logical location for video communication environment may further be defined via the administrator portal.

The Mesh Orchestrator defines a mesh of respective client computer systems associated with the one or more identified user accounts (Act 520). In some embodiments, the Mesh Orchestrator is a cloud service which defines, manages, monitors and modifies one or more mesh instances at various different logical locations. The Mesh Orchestrator is an intelligent service which evaluates mesh client computer system attributes to determine, rank and assign which client computer systems will function as a mesh parent(s) or as a mesh child upon initial mesh instantiation

For example, a mesh parent is an identified client computer system which obtains the media stream from the Mesh Orchestrator and relays the media stream to one or more mesh child client computer systems in a mesh instance for a logical location. A mesh child consumes the media stream from a mesh parent situated at the same logical location. In some embodiments, the Mesh Orchestrator may promote a mesh child to be act as a new mesh parent if mesh conditions indicate that another mesh parent should be added—or a current mesh parent should be replaced due to poor performance or unavailability.

The Mesh Orchestrator sends a child designation message to at least one mesh child (Act 530). The child designation message indicates to a particular client computer system that is has been assigned the role of being a mesh child. In addition, the child designation message further identifies a specific mesh parent from which the mesh child should request the virtual meeting stream when the virtual meeting begins. As the virtual meeting proceeds, the Mesh Orchestrator actively monitors the operation and status of the mesh instance and adjusts the roles of the client computer systems in the mesh and which peers are in use based on mesh client computer system performance.

In some embodiments, the Mesh Orchestrator instantiates a mesh instance for active media redistribution as an online webinar begins according to the parent and child role assignments. As conditions change during the online webinar, the Mesh Orchestrator actively manages the mesh instance to ensure that a maximum allowed bandwidth allocated to the video communication environment at the logical location is not oversubscribed. For example, condition changes during the online webinar observed by the Mesh Orchestrator may be based on one or more of the following: user accounts joining or leaving the online webinar, changes in network conditions at a computer system or at the logical location, computer system utilization metrics. Each mesh parent and mesh child continually sends reporting messages to the Mesh Orchestrator with data that can indicate condition changes. By continually receiving the reporting messages, the Mesh Orchestrator receives information and data to initiate mesh healing procedures to heal (i.e., update, modify, change) a mesh instance before client buffers for mesh parents and mesh children are exhausted.

In some embodiments, a mesh definition that corresponds with a logical location will assign a minimum of two parents, a primary mesh parent and a secondary mesh parent. For example, a single mesh parent may be required to be active for a mesh instance based on a mesh definition of less than ten mesh children. It is understood that ten mesh children is an example value for illustrative purposes. However, the mesh definition may further designate one or more mesh children to act as secondary mesh parent(s). A secondary mesh parent is a mesh child that will be promoted to act as a mesh parent in a mesh instance if the scale of the mesh instance increases or if a current mesh parent fails. Upon instantiation of a mesh, the Mesh Orchestrator sends an identification of a primary mesh parent(s) and a secondary mesh parent(s) to each mesh child in a child designation message.

During an on online event (e.g., virtual meeting, online webinar), if a mesh child cannot pull a media stream from a primary mesh parent, the mesh child will attempt to grab the media stream from the secondary mesh parent and send a notification to the Mesh Orchestrator that there may be a possible failure occurring at the primary mesh parent. In response to the notification, the Mesh Orchestrator may apply contingency logic to heal the mesh by redistributing mesh parent and mesh child assignments to computer systems currently active in the mesh instance.

As shown in flowchart 600 of the example of FIG. 6 , the Mesh Orchestrator selects one or more mesh parents and a mesh child (or mesh children) (Act 610). The Mesh Orchestrator accesses client computer system specific data generated by the video communication environment in order to determine which client computer systems will be designated as mesh parents and which will be mesh children. For example, the Mesh Orchestrator accesses historical virtual meeting data associated with each client computer system identified as being associated with a user account scheduled to attend the same upcoming virtual meeting and further located at (or assigned to) a particular logical location. Historical virtual meeting data may include data describing a client computer system's past performance as a mesh parent or mesh child in a previously instantiated mesh(es). Historical virtual meeting data may further include data describing an average amount of time before or after a start of a virtual meeting that the client computer system typically logs on.

When defining the mesh and selecting a mesh parent(s) and mesh children, the Mesh Orchestrator further accesses various types of system data or utilization data of each client computer system such as: client machine specifications (CPU model, total memory, storage capacity), current client machine conditions (active CPU, RAM, storage), a network connection type (wired/wifi), bandwidth, reliability, latency, peer-to-peer network connectivity and reliability as measured by bandwidth, latency and/or jitter. When instantiating a defined mesh, the Mesh Orchestrator accesses each client computer system's current availability state to determine whether the client computer system is currently available and/or currently logged onto the virtual meeting or is currently attempting to log onto the virtual meeting.

The Mesh Orchestrator runs one or more tests on the computer systems included in a mesh definition prior to initiation of the upcoming virtual meeting (Act 620). According to some embodiments, prior to initiation of the virtual meeting, the Mesh Orchestrator runs lightweight synthetic testing using video communication environment-specific video encoded to ensure the client computer systems assigned to a mesh definition will operate as expected. The client application software on each mesh client computer system reports back to the Mesh Orchestrator with data and analytics related to that computer system's performance, conditions and state during the test. It is understood that testing may be repetitively performed, such as running one or more tests every hour or every three hours (for example) prior to initiation of the upcoming virtual meeting.

The Mesh Orchestrator defines contingency logic prior to initiation of the upcoming virtual meeting (Act 630). Contingency logic includes commands for changing a mesh instance and/or mesh definition prior to or after instantiation. For example, in the event that the Mesh Orchestrator is unable to instantiate a mesh instance according to the mesh definition or the mesh instance experiences a failure, the Mesh Orchestrator executes contingency logic commands to update the mesh definition and/or mesh instance. In various embodiments, a failure may be identified when one or more of the client computer systems included in an instantiated mesh is unable to communicate with the Mesh Orchestrator.

In various embodiments, as the amount of total bandwidth allocated to the video communication environment per logical location is predetermined, the number of client computer systems in a mesh and logged onto a virtual meeting from a particular logical location is known by the Mesh Orchestrator and contingency logic may include fallback commands. Fallback commands may instruct a client computer system(s) in a mesh instance to reduce an amount of bandwidth that it uses during the virtual meeting. A fallback command may further instruct a client computer system in a mesh instance to display the virtual meeting via video communication environment client software according to a user interface layout which minimizes bandwidth consumption. For example, the Mesh Orchestrator may execute a command(s) for one or more client computer system(s) in a mesh instance to switch from a user interface grid layout to an active speaker layout. If content is being shared between client computer systems in the mesh instance, a contingency logic command may be executed to further reduce a frame rate of the shared content.

In some embodiments, the Mesh Orchestrator may apply contingency logic to determine which type of stream to be sent to a mesh parent(s). For example, depending on current availability and operational status of the computer systems in a mesh instance, the Mesh Orchestrator may select one or more of an audio content stream, a video content stream and a content stream of a virtual meeting to be transmitted to a mesh parent(s).

According to various exemplary embodiments, prior to initiation of an upcoming virtual meeting, the Mesh Orchestrator identifies one or more user accounts scheduled to participate in an upcoming virtual meeting delivered via a video communication environment. For example, the Mesh Orchestrator accesses calendar data of the video communication environment and identifies the one or more user accounts in the calendar data. For example, the calendar data may indicate one or more user accounts that have accepted invitations to attend a particular virtual meeting. The Mesh Orchestrator defines a mesh of a group of respective client computer systems at a same logical location and associated with the identified user accounts. The mesh is defined as including at least one mesh parent client computer system (“mesh parent”) and at least one mesh child client computer system (“mesh child”). In order to define the mesh, the Mesh Orchestrator identifies a first client computer system as the mesh parent based at least on the first client computer system's historical virtual meeting data. The Mesh Orchestrator identifies a second client computer system as the mesh child based at least on the second client computer system's historical virtual meeting data. In addition, the Mesh Orchestrator identifies a third client computer system as a mesh back-up parent client computer system (“mesh back-up parent”) based at least on the third client computer system's historical virtual meeting data. A mesh child is designated to receive the one or more portions of the media stream of the virtual meeting from the at least one mesh parent. A mesh parent is designated for distribution of the one or more portions of the media stream of the virtual meeting.

According to various embodiments, the Mesh Orchestrator selects, based on historical virtual meeting data, one or more mesh children to receive the one or more portions of the media stream of the virtual meeting from the at least one mesh parent. The Mesh Orchestrator also selects, based on the historical virtual meeting data, the at least one mesh parent for distribution of the one or more portions of the media stream of the virtual meeting. The historical virtual meeting data is generated by a video communication environment delivering the media stream for the upcoming virtual meeting. Historical virtual meeting data may be mesh parent performance data indicating performance metrics from distributing respective previous media streams to one or more mesh children in at least one previously implemented mesh. Historical virtual meeting data may be packet loss data associated with respective previous media streams of one or more previous virtual meetings. Historical virtual meeting data may be mesh child performance data indicating performance metrics from receiving respective previous media streams distributed by one or more mesh parents in at least one previously implemented mesh.

Prior to initiation of the upcoming virtual meeting, the Mesh Orchestrator performs one or more tests on the computer systems of the defined mesh. Prior to initiation of the upcoming virtual meeting, the Mesh Orchestrator may also define mesh contingency logic for applying one or more changes to an implemented version of the mesh (e.g., a mesh instance) during the upcoming virtual meeting. The mesh contingency logic may include one or more commands for at least one of: selecting a new mesh parent for an implemented version of the mesh during the upcoming virtual meeting, setting a maximum bandwidth for at least one client computer system in an implemented version of the mesh during the upcoming virtual meeting and setting a required upcoming virtual meeting display layout for at least one client computer system in an implemented version of the mesh during the upcoming virtual meeting.

According to various embodiments, the Mesh Orchestrator may be a cloud computing resource(s). The respective client computer systems associated with the one or more identified user accounts belong to one or more networks segments at a same logical location. For example, the logical location may be defined as allowing for a certain maximum amount of available bandwidth for the video communication environment to deliver one or more virtual meeting media streams to the respective client computer systems.

During the upcoming virtual meeting, the Mesh Orchestrator receives one or more messages from a mesh parent(s) and/or from a mesh child (or mesh children). For example, the message indicates at least one of: attendance status of the upcoming virtual meeting by the client computer system, a network condition experienced by the client computer system and a machine utilization of the client computer system. In some embodiments, the Mesh Orchestrator applies a change(s) to an active mesh instance, according to contingency logic, based on and in response to one or more of the received messages.
